PIPE CLAMP CHIMNEY COMBINATION Original Filed Oct. 15, 1936 PatentedApr. 23, 1940 UNITED STATES PATENT OFFICE Application October 15, 1936,Serial No. 105,804

Renewed September 14, 1939 3 Claims.

It is aimed to provide a novel structure and combination whereby variouspipes may be fitted to chimney openings of difierent diameters, whereinnothing protrudes into the chimney to unduly gather soot or interferewith the draft; wherein installation makes the premises more fireproofand gas proof; wherein the use of nails or wire or unsightlycontrivances to hold the pipe in place are avoided; and wherein variousstandard sizes of pipes may be connected and clamped in a novel mannerin the chimney openings of different sizes.

The more specific objects and advantages will in part be pointed outhereinafter and otherwise become apparent from a consideration of thedescription following taken in connection with accompanying drawingillustrating an operative embodiment.

In said drawing:

Figure l is a View in front elevation'showing my improvements in use inconnection with a chimney;

Figure 2 is a vertical sectional view taken on the line 22 of Figure 1;

Figure 3 is a' section taken on the line 33 of Figure 2;

Figure 4 is an enlarged section taken on the line 4-4 of Figure 1; and

Figure 5 is a detail section taken on the line 55 of Figure 4.

Referring specifically to the drawing wherein like reference charactersdesignate like or similar parts, a chimney is conventionally shown atH). having an opening ll therethrough whereby products of combustion mayreach the interior of the chimney and discharge therein. Disposed in theopening II is a thimble I2 whose inner end has a multiplicity of baselock members 13, which are bent laterally as at M to anchor the thimblein place. At the inner surface of the wall of the chimney, it is engagedby an annular ring IS.

A bracket ll, of angular form in side elevation and of U-shape in plan,is bolted or otherwise fastened as at I 8 to the ring, and clampsections l9 are pivotally connected to the bracket H, for instancehaving hinged leaves 20, fastened to the sections 19' and pivoted toportions of the bracket.

Said clamp sections l9 are of interior channel shape as shown and suchsections have lugs 2| thereon engaged by an adjustable and removableclamping bolt 23 having a nut 24 screw threaded thereon.

The stovepipe is shown at 25' and it has an annular outward bulge orswedge at'ZB at a short distance from its outer end, which end ispreferably crimped as at 21'.

It will be seen that the clamp sections are connected to the thimble andthat the ring I5 is also connected to the thimble. Said clamp sectionsare adapted to be brought together so as to enclose and engage theflange 28 which is welded to the thimble. The bolt 23 may be tightenedto the extent desired and a very tight, nonrattling and secure andefiicient joint is produced.

The invention is usually employed where the stovepipe 25' is of lessdiameter than the thimble l2. An adapter generally designated A isemployed and it comprises an annular plate 30 and within the chimneybeing lined with asbestos as at 3|. The device uses a plurality,preferably four clips 32 which are riveted at 33 to. the plate 30. Theclips 32 have lugs 34, bent into retaining engagement with the asbestos3|, and the clips 32 are extended to form guides 35, which engage theinner wall of the thimble I2.

The terminal of the thimble 12 has an outwardly flaring annular flangeas at 28', beyond the ring of the thimble. Adapted to abut the flange 28is a curled marginal portion 36 of the plate'30, such flange 28 andmarginal portion 36 being engaged and clamped in place by the clampsections l9.

The aforesaid stovepipe 25' is adapted to be passed through the centralopening of the plate 30 and the asbestos 31 and in order to fasten thesame in place the adapter has an outwardly flared flange 31 whichengages the bulge 26'. In addition, the adapter has hinged thereto at abracket l1, identical with the bracket IT, a pair of clamp sections 38,of interior channel form, which embrace the flange 31 and the bulge 26',the same being fastened together by a suitable bolt at 39 operating andmounted identically with the bolt and nut at 23 and 24.

It will be realized that pipes such as 25', of different diameters areaccommodated in a chimney opening and thimble of a larger size.

.The asbestos 3| is employed so as to eliminate disco-loring of thefaces of the plate 30 or the equivalent.

Obviously the various parts constituting the invention are simple andfor the most part may be stamped from sheet metal and readily formedinto shape inexpensively. The metal may be as heavy as desired anddifferent parts such as the jury from suffocation.

I claim as my invention:

1. A device of the class described comprising a I thimble having anoutwardly flaredflange at one end, a ring surrounding the thimble andsecured thereto adjacent said flange, an adapter member having a portionto abut said flange, clamping, sections pivoted to the ring andsurrounding said flange and portion, and means on the adapter to fastena pipe therein.

2. A device of the class described comprising a thimble having anoutwardly flared flange at one end, a ring surrounding the thimble andsecured thereto adjacent said flange, an adapter member having a portionto abut said flange, clamping sections pivoted to the ring andsurrounding said flange and portion, means on the adapter to fasten apipe therein, comprising clamp sections pivoted to the adapter, the pipehaving a bulge, and the clamp sections being interiorly channeled toengage said bulge.

3. A device of the class described comprising a thimble having anoutwardly flared flange at oneend, a ring surrounding the thimble andsecured thereto adjacent said flange, an adapter member having a portionto abut said flange, clamping sections pivoted to the ring andsurrounding'said flange and portion, means on the adapter to fasten apipe therein, comprising clamp sections pivoted to the adapter, the pipehaving a bulge, and the clamp sections being interiorly channeled toengage said bulge, asbestos on the interior of the adapter, clipssecuring extending therefrom and engaging the thimble.
